When you are young, I think, your hearing is in some ways better than it is ever going to be again. You hear better than most people the voices that call to you out of your own life to give yourself to this work or that work.

When you are young, before you accumulate responsibilities, you are freer than most people to choose among all the voices and to answer the one that speaks most powerfully to who you are and to what you really want to do with your life.

But the danger is that there are so many voices, and they all in their ways sound so promising.
